Re: Creating a UI thread with CWinThread

The second version wants a subclassed CWinThread, but I'm not sure where exactly to place my code in it. May be in InitInstance. Any suggestions?

I already have the worker thread and the code for it, I need to know what to change to make showing modal CDialogs possible.

The second link shows common CWinThread overrides
and what those overrides should do.

Hi.I'm using visual c++ 9.0.
I want to do something like this:

string name = get_name();
string filename = name+("text.dat");

ifstream infile_file;

infile_file.open(filename);
(code)
(...)

I'm doing something wrong... or I am missing something.
Here is the error:
error C2664: 'void std::basic_ifstream<_Elem,_Traits>::open(const wchar_t *,std::ios_base::openmode,int)' : cannot convert parameter 1 from 'std::string' to 'const wchar_t *'
with
[
_Elem=char,
_Traits=std::char_traits<char>
]
No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called
Thanks.

this is because you're building your appblication in UNICODE most probably...

~~try removing the declaration of that macro and rebuild.~~

forget that. std::string::c_str() is the way to go

If the xlsx file is an XML file then probably not.

Do you have a C++ or MFC question?

You won't get any WM_MOUSEMOVE messages in your dialog if you've set
capture to another window.

No error at all but to Copy file..

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
